I need help answering 1-4.

Data from 2 ft. drop: 1.5 2 3 2.5 4 1 2 3.5 3 2 1 3.5 3 5 4 2.5 4 6 7 1 3 6 2.5 5 4 6 1.5 1.5 1 6

Data from 4 ft. drop: 12 21 6 6.5 4.5 11 5 3 6 9 3.5 7.5 9 7.5 9.5 6.5 5 3.5 9 6.5 7 4 6.5 7.5 5.5 4.5 8.5 2.5 4 5.5

1. WE WILL CALCULATE ONE STATISTIC THIS EARLY IN THE COURSE: THE MEAN (AVERAGE). ADD UP EACH SET OF DISTANCES AND DIVIDE EACH OF THOSE SETS BY 30 (THE NUMBER OF DATA POINTS IN EACH SET) TO GET THE MEAN. MATHEMATICALLY THIS WOULD BE SHOWN AS: m = Σx/n WHERE "x" IS EACH DATA POINT AND "n" IS THE TOTAL NUMBER OF DATA POINTS INVOLVED. (MATH IS REALLY LIKE ANOTHER LANGUAGE WITH ITS OWN SYMBOLS AND CONTEXT)
2. NOW, ON YOUR TWO DATA PLOTS DRAW A HORIZONTAL LINE WHERE YOUR CALCULATED MEAN IS. SEE HOW SOME DATA POINTS ARE ABOVE THIS LINE AND SOME BELOW? MEASURE THESE 30 DISTANCES WITH THE DISTANCES ABOVE THE LINE AS POSITIVE NUMBERS AND THOSE BELOW THE LINE AS NEGATIVE NUMBERS. ADD THEM ALL UP AND WHAT VALUE DO YOU GET? (RATHER THAN MEASURING SIMPLY SUBTRACT YOU CALCULATED MEAN FROM EACH DATA MEASUREMENT).
3.  BOTTOM LINE: LOOK AGAIN AT EACH PLOT AND HOW THE TWO SETS OF DATA PLOTS ARE SCATTERED AROUND THE MEAN. DO THE PLOTS, THE CALCULATED MEAN OR THE TWO ROWS OF NUMBERS TELL YOU ANYTHING ABOUT THE DIFFERENCES THE DROP HEIGHT MAKES AND WHETHER IT CONFORMS TO THE F = MA FORMULA? EXPLAIN THIS IN YOUR POST.
4. FOR REVIEWS (2 REQUIRED), NOTE HOW YOUR OBSERVATIONS AGREE/DISAGREE WITH YOUR CLASSMATES - BUT LOOK FOR CLASSMATE POSTS THAT DIFFER AT LEAST SOMEWHAT FROM YOURS SO THAT YOU EITHER GET A NEW PERSPECTIVE, OR CAN HELP THEM WITH THEIR INTERPRETATION.
